The following topics are covered:

• Solubility in water in general
• Conditions governing solubility in water
• Water-soluble and water-insoluble substances
• Reversing the dissolving process
  through crystallization
• Thermal changes caused by dissolving
  substances in water
• Changes in viscosity caused by dissolving
  substances in water
• Formation of gas caused by dissolving
  substances in water

 
Teacher’s manual ‘What happens when we mix water with ...?’

• The manual includes basic information on the topic and the organization of workstations for the teacher.
  It also contains information about the scientific background, didactic notes on each experiment and student worksheets.
• Including a list of materials and rules for experiments.

 
With copy templates covering 10 workstations.

• 1 - Water and sugar – in large quantities

  experiment "Water and sugar – in large quantities"

  These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.

  
  
• 2 - Water and urea

  experiment "Water and urea"

  This experiment lets students investigate the thermal changes that occur when certain substances are added to water.

  
  
• 3 - Tea and sugar

  experiment "Tea and sugar"

  The first experiment is designed for students with no previous experience of experiments. It uses common household materials. At this stage, the topic reflects everyday experiences and is an introduction to acting and thinking scientifically.

  
  
• 4 - Water and sugar

  experiment "Water and sugar"

  In this second experiment the students encounter the same phenomena, but with a stronger emphasis on laboratory-style work.

  
  
• 5 - Water and sugar – with and without stirring

  experiment "Water and sugar – with and without stirring"

  These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.

  
  
• 6 - Water and sugar – warm and cold

  experiment "Water and sugar – warm and cold"

  These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.

  
  
• 7 - Water and various substances

  experiment "Water and various substances"

  These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.

  
  
• 8 - Water and salt

  experiment "Water and salt"

  This experiment revisits the theme of solubility before moving on to crystallization.

  
  
• 9 - Water and gelling agents

  experiment "Water and gelling agents"

  This experiment looks at the solidification of water caused by the addition of substances that form a gel.

  
  
• 10 - Water and sherbet

  experiment "Water and sherbet"

  This experiment leads into a new chapter of Research and Explore focusing on “sherbet”.
